this reminds me a lot of Observation 247810 & Observation 247787, which aren’t far from this sighting. I would suggest that the vertical striations from fissures in the ecostroma (to borrow a new vocab word from your blog post :) ) and the sterile, pointed tips seem to point more in the direction of the X. apiculata group, but Bjorn IDed those afore-linked posts as X. longiana (= X. hypoxylon?), and these characteristics also form a part of Rogers’ X. cornu-damae description. Does that make both X. longiana/X. hypoxylon and X. cornu-damae members of the X. apiculata group, or am I missing something?

Xylaria digitata

My understanding of Xylaria digitata is that it’s pricipally European. Sterile accuminate tips and the long pieces of conidial coat seem to make this X. cornu-damae, but see that paper in the reference, which talks specifically about USA species that might be easily confused with Xylaria digitata.

If you’ve got specimens, you might want to cut one open and see how big the perithecia are, and if you’ve got access to a microscope, see whether the spores have germ slits that are the full length of the spore, or relatively short. Those features will let you say what it is for sure.

Good find! And good luck!

Best way to get an ID — propose a species, & let the fun begin
